Abstract

Percussion device including a machine housing ( 1 ),' a forwards and backwards movable percussion piston ( 2 ) in the machine housing, and a reciprocatingly movable valve body ( 6 ) in the machine housing, said percussion piston ( 2 ) being arranged to, subject a tool ( 3 )' to impacts, and said percussion piston including a first ( 4 ) and a second ( 5 ) driving surface intended to be subjected to pressure in order to drive the percussion piston ( 2 ), forwards and backwards, said valve body ** ( 6 ) including a first end surface ( 12 ) and a second end surface ( 13 ), wherein the pressurizing of the first end surface ( 12 ) tends to drive the valve body in a first direction and pressurizing of the second end surface ( 13 ), tends to drive the valve body in a second direction, whereby the valve body ( 6 ) is arranged, over a channel ( 7 ) arranged in the machine housing, to connect at least the second ( 5 ) of the driving surfaces alternately to a pressure source ( 8 ) or to low pressure ( 9 ), wherein the second end surface ( 13 ), by the percussion piston ( 2 ), is alternately connectable to the pressure source ( 8 ) or, over a valve device ( 11 ) for creating a counter-pressure, to the low pressure ( 8 ).
